Definitions

  • the present invention relates to disc brakes for vehicles, and in particular to a system and method for mounting and retaining brake pads in disc brakes, such as air-operated disc brakes utilized on commercial vehicles.
  • German Patent Publication No. DE 40 32 886 A1 discloses an example of such an air disc brake.
  • a pneumatic diaphragm chamber (pneumatic actuator) is attached to a rear face of the disc brake caliper housing, and applies a brake actuation force through a linear actuator rod to a brake actuator lever within the caliper.
  • the brake's actuator lever in turn transfers and multiplies the force applied by the actuator rod to one or more spindles, which force brake pads against a brake disc or rotor.
  • the terms “brake disc,” “rotor” and “brake rotor” are used interchangeably herein.
  • the actuator is located inboard of the brake caliper, in large part because commercial vehicle wheel rims are sized to only provide adequate clearance for the drum-type brakes historically employed on such vehicles. Because the resulting space envelope between the wheel and its axle is limited, the actuator must be located into the space adjacent to the wheel. For the same reason, brake pads must be configured to conform to the limited available radial space, and thus have typically been located and retained on one of the brake caliper or brake caliper carrier/mount using transverse suspension pins and/or using leaf spring-type metal strips disposed over the outer radius of the brake pads.
  • Brake pads have also been retained by capturing the brake pads between the caliper mounting frame and the portion of the brake caliper which straddles the brake disk.
  • the same brake pad support function may be provided by a brake caliper carrier/mount designed to support the brake pads or by a brake pad carrier which is separate from the caliper mounting structure.
  • the terms caliper carrier, caliper mount and brake pad carrier may be interchanged without intending to limit the brake pad supporting structure to any specific brake pad and brake caliper carrying structure.
  • DE 196 10 611 A1 discloses a brake pad retention mechanisms, where brake pads are hold on a brake caliper and wherein each of the brake pads are engaged with a brake pad carrier by a spring clip having a portion on top that wraps around a brake pad lateral protrusion, and a lower portion that engages a lower surface of a projection of the brake pad carrier.
  • a further problem with prior art brake pads is the tendency for the brake pad to rotate and/or vibrate during brake operation.
  • a brake pad 101 when a brake pad 101 is applied against a friction surface of a brake disk (not illustrated) which is rotating in direction DR, the brake disk's rotation induces motion and reaction forces between the brake pad 101 and its adjacent mount abutment surfaces (not illustrated for clarity).
  • the brake pad attempts to move upward in direction LU in response to the friction forces along the face of the brake pad (illustrated here by force arrows across the face of brake pad 101).
  • the brake pad attempts to move downward in direction TD.
  • the overall motion of the brake pad is generally a rotation about an axis parallel to the brake disk rotation axis. This motion may be unilateral during the brake application, or may manifest itself as a moderate-to-severe oscillation of the brake pad in its mount, significantly increasing wear of the abutting brake pad and mount surfaces.
  • the brake pad backing plate and the adjacent mounting bracket horns supporting the brake pads in the circumferential direction required a relatively tall radial height to minimize the amount of brake pad rotation before a corner of the backing plate contacted the adjacent mount horn (a motion referred to as "pad kick" or “pad turnout,” caused by “twisting” or “tipping” of the pad in the caliper as the rotating brake disk attempts to raise one end of the brake pad while pushing down on the other end of the brake pad).
  • Document DE19610611 A1 discloses an example of a brake pad retention system for a disc brake.
  • the present invention addresses these and other problems by providing a brake pad mounting and retention system according to claim 1 which provides for minimum pad kick motion, elimination of the need for over-topping brake pad retention devices, inherently vibration- and noise-reducing mounting, and lower mount horn height which in turn permits increased brake caliper strength and service life Furthermore a brake pad retention element, a brake pad carrier and a brake pad according to claims 9, 15 and 17, respectively, are provided.
  • a brake pad is provided with slots on its lateral and bottom edges arranged to receive a correspondingly-shaped spring element.
  • the spring element in turn has side extensions, such as 4 tabs, which conform to the width of the brake pad carrier and serve to both align and guide the brake pad into position during installation and lock the spring element into place against lateral motion toward or away from the brake disc as the brake pad is advanced or withdrawn from the brake disc.
  • the spring element is further provided with a retention feature on a top surface which may engage a corresponding slot or relief in the pad-side face of the adjacent mount's horn.
  • the retention feature may be an angled tab which permits the brake pad and spring element to be inserted as an assembly vertically downward (i.e., radially inward toward the vehicle axle) in to the mount until the upper retaining feature reaches its corresponding mount relief and elastically springs outward.
  • the brake pad is retained in the brake in a simple and positive manner by the combination of: (i) the upper retention feature snapping into the mount relief; and (ii) the spring element having a protrusion which extends into one of the slots in the edge of the brake pad.
  • a further extension of the spring element which engages the slot on the lower edge of the brake pad may also be provided to assist in retaining the spring element on the brake pad before the brake pad is inserted into the mount.
  • This arrangement further has the advantage of taking up brake pad-to-mount clearance at the sides of the brake pad, such that brake pad rotation within the mount ("pad kick") is significantly limited.
  • the limited rotation motion reduces the need for tall mount horns to control brake pad rotation, thereby permitting shorter horns and in turn thicker brake caliper sections above the horns to increase caliper fatigue and service life.
  • the arrangement also eliminates the need for space-taking over-topping brake pad retention devices.
  • inventive spring retention element provides a replaceable wear surface which protects the facing surfaces of the mount horns from wear, extending mount service life.
  • the inventive brake pad and spring retention device may be provided on only one side of the brake pad, or on both lateral sides to further reduce pad rotation motion.
  • the spring retention device is preferably formed from high-strength material, preferably heat-treated spring steel, and includes a pad vibration-reducing tension tab. Such an element is easily and cost-effectively produced, for example by a metal-stamping process.
  • the spring element protrusion which engages the side of the brake pad is preferably formed in a wedge-shape which resists "camming out” of the brake pad slot during the brake application.
  • a disc brake 1 of a commercial vehicle includes a brake disk 2, a brake caliper 3 straddling the brake disk 2.
  • the brake disk 2 rotates in the direction A about axis B when the vehicle is moving in a forward direction.
  • the caliper 3 is affixed to a mounting carrier 6 which in turn is fixed to a vehicle axle, typically via a torque plate or a brake spider (not illustrated).
  • the caliper 3 is actuated by an actuator 5, in this embodiment a spring brake actuator which is controlled by pneumatic pressure from the vehicle.
  • the actuator 5 acts upon a brake pad application mechanism contained within caliper 3 to press brake pads 4 against the brake disk 2 to slow the vehicle.
  • the present invention is not restricted a particular type of brake caliper/mount arrangement (for example, a fixed carrier and a sliding caliper with a single-side brake pad application mechanism, or a fixed carrier and fixed caliper with two-sided brake pad application mechanisms).
  • Fig. 3 shows an elevation view of a mount 6 and a brake application-side brake pad 4.
  • the mount need not be a caliper-supporting carrier, i.e., the caliper may be mounted on a component separate from the mount, with only the brake pads being carried by the mount.
  • the mount 6 includes horns 10 having brake pad contact faces 11. During brake application, the contact faces 11 support and receive loads transferred from a brake rotor (not illustrated) rotating in direction DR through the lateral sides 12 of the brake pad 4 to the mount 6.
  • one spring element 15 is provided on one lateral side of the brake pad 4.
  • a second spring element may be provided on the opposite lateral side of the brake pad 4, as shown for example in Fig. 6 .
  • the brake pad 4 may also include additional features, such as a slot 60 for receiving a brake pad wear sensor (not illustrated for clarity).
  • FIG. 4 A detailed view the region indicated by the letter "A' in Fig. 3 is shown in Fig. 4 , and an oblique view of the spring element 15 shown in Figs. 3 and 4 is illustrated in Fig. 5 .
  • Fig. 4 shows a detailed view of the region in which the spring element 15 is positioned between the brake pad 4 and the mount 6.
  • the spring element 15 has a plurality of alignment tabs 16, which are spaced to conform to the sides of mount face 11 to guide the brake pad 4 into position during brake pad installation in mount 6, as well as helping minimize back-and-forth movement of the spring.
  • the spring element 15 also in this embodiment includes two retention features, a pad locking track 17 which engages a corresponding slot 19 in the lateral side of the brake pad 4, and a retaining tab 18 which engages a corresponding slot 20 on the lower edge of the brake pad 4.
  • the spring element 15, pad locking track 17 and retaining tab 18 are preferably arranged such that the spring element 15 is self-retaining on brake pad 4 by elastic bending around the lower corner of the brake pad.
  • the spring element 15 also includes a tension tab 21 to take up free play between the lower edge of the brake pad 4 and the mount 6, in order to suppress vibrations of the brake pad against the mount.
  • an end portion 22 is angled outward away from the lateral side of the brake pad 4. As the brake pad is inserted into the mount 6, the end portion 22 is pressed elastically toward the brake pad 4 by the upper end 23 of the mount horn 10 until the end portion 22 reaches a lock profile 24 in the mount face 11. Once the end portion 22 is engaged in the lock profile 24, it cooperates with the mount horn 10 and the pad locking track 17 to retain the brake pad 4 in the mount 6 without the need for any pad retention mechanism over-topping the brake pad.
  • a locking tab may be formed from a central region of the end portion 22, similar to the shape of the tension tab 21 shown in Fig. 5 , to perform the pad retaining function.
  • a hole 25 in the top of the mount horn 10 which passes through to the lock profile 24.
  • a pin or other similar tool may be inserted into the hole 25 to press the end portion 22 toward the lateral side of brake pad 4 until the end portion 22 is free to pass upward along mount horn face 11.
  • disengagement approaches such as extending a tab from the end portion 22 radially outward or inward (see Fig. 7 ), where the tab may be pressed toward the lateral edge of the brake pad 4 to disengage the end portion 22 from the lock profile 24 without requiring the use of a spring element disengaging tool.
  • the lower spring element retaining tab 18 and its corresponding slot 20 may be omitted from the brake pad 4. Even without the retaining tab 18, the spring element 15 may be self-retaining on the brake pad if the pad locking track 17 and the bottom leg portion of the spring element 15 are separated by a distance which results in the spring element 15 being under sufficient tension when placed on the brake pad 4. In the case where the spring element 15 is not self-retaining, the retaining tab 18 and corresponding slot 20 still may be omitted, as the spring element 15 may be manually held to the brake pad 4 during brake pad installation, and the brake pad retention function will still be provided by the pad locking track 17 and spring element end region 22 once the brake pad 4 reaches its installed position.
  • the spring element may also be affixed to the brake pad by other approaches, such as crimping of brake pad-facing retention tabs similar to alignment tabs 16 to the lateral edge of the brake pad.
  • the portion of the spring element below the brake pad lower edge may be omitted if the spring element and its protrusions are sized large enough to maintain a stable brake pad orientation during brake operation.
  • One of the features of the arrangement illustrated in Figs. 3-5 is that there is no constraint against sliding motion of the brake pad 4 in the direction parallel to the brake disc rotation axis (i.e., toward or away from the brake disc) while spring element 15's alignment tabs 16 hold the spring element to the mount horn 10.
  • the width of the spring element 15 in the direction parallel to the brake disc rotation axis must be sufficient to ensure that as the brake pad 4 wears, the brake pad cannot slide so far towards the brake disc that the pad locking track 17 disengages the corresponding slot 19 in the brake pad 4, such that the brake pad would possibly migrate radially outward from the mount 6.
  • Fig. 6 is a plan view of two opposing brake pads 4 positioned in mount 6. This figure illustrates the arrangement of the alignment tabs 16 of spring element 15 along the sides of mount horn face 11 and along the lower edge of the mount 6 to guide the brake pad 4 into the mount 6 and to prevent the spring element 15 from moving toward or away from the brake disc (not illustrated). As shown in this figure, the width of the spring element 15 is sufficient to ensure the backing plates 26 of the brake pads 4 will not slide out of the spring element 15 toward the brake disc, even when the brake pad has been worn to the point of removing all of the brake pad lining material 27 from the backing plate 26.
  • Figs. 7-10 show alternative spring element embodiments.
  • Figs. 7 , 8a and 8b illustrate an embodiment in which the spring element end region 22 includes an aperture 28, and the upper end 23 of the mount horn 10 includes a corresponding hook-shaped portion 30 which engages the spring element 15 through the aperture 28.
  • the upper end of the end region 22 is located alongside a connecting portion 29 of the caliper which extends over the brake disc, where in may easily be reached to be pressed toward the center of brake pad 4 to disengage the hook-shaped portion 30 for withdrawal of the brake pad from the mount 6.
  • the upper end of the spring element 15's end region 22 may be configured to fit under the lower surface of the caliper connecting portion 29.
  • FIG. 10 An additional embodiment is shown in Fig. 10 , in which the end portion 22 of spring element 15 is configured to generally conform to the shape of the upper corner of brake pad 4, and is provided with a tab 31 which may be used to deflect the upper end of end portion 22 away from brake pad 4 until it disengages from the hook-shaped portion 30 at the top of mount 10 to permit withdrawal of the brake pad 4.
  • a locking feature such as a tab or protrusion from the spring element may engage a lock profile much closer to the bottom of the mount horn.
